[0023] In this embodiment, the connecting column 37 is a threaded column with threads on the outer circumference, so the distance between the first guide rail 31 and the second guide rail 32 can be freely adjusted as needed. The second resilient component 34 is used to fix the second guide rail 32 on the outer cylinder 1. In this embodiment, since the second resilient component 34 has the same structure as the first resilient component 33, its structure is not repeated here. It can be understood that in an embodiment, the second resilient component 34 may not be provided.

[0024] During use, the bottle cap is allowed to slide down smoothly through an external oscillating device. When the external oscillating device is stopped, without the first resilient component 33 and the second resilient component 34, the first guide rail 31 and the second guide rail 32 will not return to their original positions, and the bottle cap will be hindered when sliding down. Therefore, a pulling force is provided by the first resilient component 33 and / or the second resilient component 34 to pull the first guide rail 31 and / or the second guide rail 32 to their original positions, and the bottle cap can slide down smoothly.

[0025] Preferably, the outer cylinder 1 is provided with a receiving hole 12 corresponding to the positions of the first guide rail 31 and the second guide rail 32, the first side of the first guide rail 31 is movably inserted in the receiving hole 12, the second side of the first guide rail 31 extends into the cylinder hole 11, and the second side of the first guide rail 31 is provided with an arc-shaped bottle cap contact surface facing the second guide rail 32.

Therefore, not only the first guide rail 31 and the second guide rail 32 are more reliably positioned, but also the arc-shaped bottle cap contact surface contacts the bottle cap, thereby better avoiding scratching the bottle cap and better guiding the movement of the bottle cap.

[0026] Preferably, the first inlet guide block 21 is provided with a first slot 211 communicating with the bottle cap delivery channel a, and the upper end of the first guide rail 31 is inserted into the first slot 211, thereby avoiding the problem of bottle caps not being able to connect during movement and causing jamming. The second inlet guide block 22 is provided with a second slot 221 communicating with the bottle cap delivery channel a, and the upper end of the second guide rail 32 is inserted into the second slot 221.

[0027] Preferably, the upper end of the first guide rail 31 is provided with a first limiting step 311, and the first limiting step 311 abuts against the lower end surface of the first inlet guide block 21, so that the structure is compact and the connection is reliable. The side of the first guide rail 31 is provided with an inclined groove (not shown in the figure) for guiding the bottle cap to slide down, so that when the bottle cap cannot slide down smoothly, it can be shaken by an external shaking device to make the bottle cap slide down smoothly.

By providing the guide key 23, a certain entry angle can be given to the bottle cap, thereby reducing the effective stroke of the bottle cap correction. In this embodiment, the angle formed by the surface where the first guide surface 231 and the second guide surface 232 of the guide key 23 are located and the surface where the bottle cap conveying channel a is located is an acute angle, specifically, it is 16.7°.

[0029] Preferably, the upper end of the sub-covering piece 4 is smaller than the lower end of the sub-covering piece 4, and the sub-covering piece 4 is provided with a first turning bevel 41 and a second turning bevel 42, the first turning bevel 41 is arranged facing the first guide rail 31 and is spaced from the first guide rail 31 by a first preset distance, the second turning bevel 42 is arranged facing the second guide rail 32 and is spaced from the second guide rail 32 by a second preset distance, the first turning bevel 41 is arranged facing the first guide rail 31 and cooperates with the first guide rail 31, and cooperates with the second guide rail 32 through the second turning bevel 42, so that the bottle cap can be rotated better. In addition, since the upper end of the sub-covering piece 4 is smaller than the lower end of the sub-covering piece 4, the bottle cap can be better prevented from getting stuck. In this embodiment, the cross section of the sub-covering piece 4 is arc-shaped, and the sub-covering piece 4 is located directly below 31 of the guide key 23.

[0030] Preferably, the outlet guide device 5 comprises two outlet guide rails 51 arranged in opposite positions, the upper ends of the outlet guide rails 51 are provided with ridges 511, the ridges 511 of the two outlet guide rails 51 are arranged facing each other, both sides of each ridge 511 are formed with third turning inclined planes 512, and the lower end of each outlet guide rail 51 is provided with a vertical surface 513 connected with the third turning inclined planes 512. The outlet guide rail device 3 cooperates with the tail ends of the first guide rail 31 and the second guide rail 32 in the inlet guide device 2. When the bottle cap rotates to the tail end parts of the first guide rail 31 and the second guide rail 32 in the inlet guide device 2, the upper end of the outlet guide rail device 3 is used to avoid contacting the bottle cap and causing a stuck result. After the bottle cap rotates through the first guide rail 31 and the second guide rail 32 in the inlet guide device 2, the ridge 511 in the outlet guide device 3 acts as a section of the guide rail 51. The function of the rear half of the outlet guide device 3 is to allow the bottle cap to contact the ridge 511 in the outlet guide device 3, rotate and correct part of the angle, and pass through a small section of the vertical surface of the outlet guide device 3, and smoothly rotate out of the outlet of the outlet guide device 35. The two outlet guide rails 51 of the outlet guide device 3 are relatively installed to form a channel that can only pass one bottle cap, and the function is to allow only one bottle cap to pass through, and avoid two or more bottle caps being squeezed and caused to get stuck.
